Defining a Characteristic

The choice of characteristic defines th

e limits for measuring underrange and overrange.

Measuring underranges or overranges outside the specified range cannot be analyzed.

If measuring ranges are undercut or exceeded, the minimum or maximum value is

issued constantly.

Sele

ct the characteristic using the  or  buttons.

2. Select the characteristic 4 - 20 unlim

ited.

For the characteristic 4 - 20 unlimited, measuring underranges are

analyzed linearly up to 0

mA, and measuring overranges are analyzed linearly

up to approx. 23 mA by the device.

3. Select the characteristic 4 - 20 NE43.

For the characteristic 4 - 20 NE43

, measuring underranges are analyzed linearly

up to 3.8 mA, and measuring overranges are analyzed linearly up to 20.5 mA by the

device.

4. Confirm your entry with OK.

Defining the Start Value

Make sure during configuration that the start value is at l

east 1% less than the end value.

If the start value does not meet this requirement, the start value will not be accepted by

the device.

1. Enter the start value as

a floating point figure. For entering floating point figures, see

"Entering Floating Point Figures" . The defined unit from the Unit

menu is used as the unit.

2. Confirm your entry with OK.

Make sure during configuration that the end value is at least 1 % greater than the start value.

1. Enter the end value

as a floating point figure. For entering floating point figures,

see "Entering Floating Point Figures" . The defined unit from the Unit menu

is used as the unit.

2. Confirm your entry with OK.
